Chicago Data Collaborative

The Chicago Data Collaborative is a cooperative effort by newsrooms, academics, and nonprofit researchers to help each other understand our criminal justice system. Collaborative members collect data from institutions at all points of contact in the Cook County criminal justice system, including the Chicago Police Department, the Illinois State Police, the Office of the State's Attorney, and the Cook County Jail.
